I don’t know if it’s just a problem with my computer, or…
basically I download it from Jenkins using the “cataclysmdda-0.9.zip” link, I’ve tried opening it with winrar and saving it, and each time it tells me the .zip is corrupted.
and sometimes you just have to wait for another experimental to be released. they’re released several times a day, so just go play Skyrim and check back later.
I have had this exact same problem in the past, winrar is not a factor, its actually your internet connection terminating the download before its actually completed for some reason or another.
there’s also the possibilities of the last experimental build not being completely built. There’s an indicator somewhere on the top right that shows you that.
